SNOWS-3: Deep Seismic Survey Data for the Offshore Canning Basin

A 1993 marine seismic survey acquired at least 3000 km of high-quality data to determine the deep crustal structure of the southern North West Shelf. The Australian Geological Survey Organisation (AGSO) conducted this third survey in a multi-cruise program, tying it to principal exploration wells and previous regional surveys. Recording parameters included a 4800 m streamer and a 49-litre airgun source, with data showing reflections down to 12 seconds two-way time.

Use Cases

• Model regional structural frameworks based on deep-seismic acquisition lines.
• Assess crustal control on hydrocarbon field development based on the survey's stated aims.
• Correlate seismic data regionally using tie lines to exploration wells.
• Analyze basin structure down to 10-12 seconds two-way time based on previous survey results.

Strengths

• High-quality seismic data with a planned acquisition of at least 3000 km along regional lines.
• Data tied to principal exploration wells and connected to previous SNOWS-1 and SNOWS-2 surveys.
• Specific recording parameters described, including a 4800 m streamer and 16-second record length.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a 1993 survey focused on a specific offshore region.
